BASKET FOR HOLDING .TAIN SCRAPS.

4SIECIFICATION forming' part of Letters` Panb No. 734,894, dated July 28, 1903. Application tiled NovemberZ, 1902. Serial No. 132,720. (No model.)

To all whom it may concern: Be it known that we, MARTIN LAERNOES, a

` citizen of the Netherlands, and JOHN DUNN, a-

citizen of the United States of America, both 5` residing in Streator, in the county of Lasalle ,g land State of Illinois, have invented certain new and useful Improvements in Baskets for Holding Tin Scraps, of which the followingis a specification. Y to This invention relates to certain improvements in` baskets for holding tin scraps while the same are submerged 'in the bathfor re- `.moving the tin onthe scraps by the action of y theelectric current, said basketsl being so I5`constructed that the fuses can be renewed with great facility and at small expense without breaking the iron or steel frame of the basket or cutting the rivets of the same, as has been the case heretofore in the baskets zo heretofore in use `in the process of detinning scraps by the electric process, so thata greater "i durability is impartedto the baskets and that the same can be used for a great length of time Without deterioration; and for this purpose the invention consists of a basket made of perforated `sheet metal and reinforcing angle-irons at the corners, the corner angle-irons being extended in the shape of yokes over the side walls of the basket and provided 3o with laterally-extending handles, one handle J serving as the cond uctorfor the electric current and being bolted to the yoke-shaped an- `gle-iron, but separated therefrom by means of layers of tin or tin-foil that are interposed between` the shank ot' the handle and` the yoke-shaped iron, said layers acting as fuses. In the accompanying drawings,Figure 1 is y aperspective viewof our improved basket `for holdingtin scraps, shown in position in 4o the bath in which the detinning process is carried on. Fig. 2 is a vertical transverse section on line 2 2, Fig. 1, drawn on a larger scale.

yoke or bail of the Fig. 3 is a'horizontal section of the removed by the action of the electric current.

The basket is suspended in the vat B, containing a suitable electrolytic solution. The. side walls of the basket A are composed of perforated sheet metal, either iron or steel, and preferably made of square shape but 6o which may also be made of round, hexagonal, or other shape. The perforated side walls g of the basket are reinforced at the corner by angle-irons along its side and bottom edges, said angle-irons vbeing riveted to the perforated side walls and bottom. The up-` per ends of the two opposite corner angleirons are extended so as to formY yokes or bails, as shown in Fig. l, by which the basket can lbe suspended in the detinning-vat, one 7o Ayoke or bail d being connected with a laterally-extending handle e, which forms contact with the rail e', that conducts the current to the handle and basket into the solution in the vat. The opposite yoke or bail CZ isalso provided with a laterally-extending handlef and rests on a wooden block b, applied tothe upper edge of the opposite side wall of the vat, as shown clearly in Figs. and 2. These corner angle-irons are preferably welded to 8o squareiron or steel yoke-shaped bars,towhich the laterally-projecting handles are applied. One of the handles is welded `to one of the yokes', so as to form one piece, whereas the O ther'yoke is provided with laterally-project 85 ing flanges, between which is inserted, bolted, or otherwise attached the other` handle.

The shank of the handle e, which serves as a conductor of the electric current, is preferably bolted to the upper ends of the yoke or 9o bail cl, as shown in Fig. 4. Between the shank ofthe handle c and the npper ends of the yoke or bail d are interposed layers of tin or tin-foil es, which act as fuses, so as to :melt in case a current of greater than the required strength passes through the vat. These tinfoil fuses can be readily replaced by loosening the nut fastening the bolts and removing the melted layers of tin or tin-foil and replacing them by new layers. 'Between the shank e and conductor e' is also placed fuse e4. By this arrangement the basket is protected against deterioration by the current and the basket readily repaired Without breaking up the frame or cutting the rivets of the basket, so'that the basket can be used until its side Walls become gradually-worn by continued usage, so that the saine have to be replaced and new baskets substituted for the vworn-out baskets.

Having thus described our invention, we claim as new and desire to secure by Letters Patentl. A basket for holding tin scraps, consisting of perforated side and bottom walls, reinforcing-irons at the corners, yokes or bails at the upper ends ofy said basket, laterallyextending handles attached to said hails, one of said handles being a conductor for the electric current and separated from the upper ends of the yoke or bail by layers of tin or tin-foil, the shank of said handle being attached to the upper ends of the yoke or bail by fastening-bolts, substantially as set forth.

2. A basket for holding tin scraps during the detinning process, consisting of a body composed of perforated sheet metal reinforced by corner angle-irons, yoke-shaped supports at their upper ends, and handles extending laterally from said supportingyokes, one of said handles being used as a conductor and connected by intermediate layers of tin or tin-foil or other fusible metal and fastening-bolts with the upper ends of the yoke, substantially as set forth.

In testimony that We claim the foregoing as our invention we have signed our names in presence of two subscribing witnesses.
